Farah collapses as he crosses line in Dublin in December
Britain's Mo Farah has been instructed to take dietary supplements after tests revealed he has lower than normal levels of iron and magnesium.
Farah underwent examination on Monday after requiring medical attention at the end of two recent races.
However, Farah's manager says the 26-year-old's training will be unaffected.
"He will leave for warm weather training as scheduled and is looking forward to continuing training as planned," said Ricky Simms.
In December, Farah was carried off on a stretcher after collapsing with exhaustion following a duel with Spanish winner Alemayehu Bezabeh at the European Cross Country Championships in Ireland.

He was again in distress as he crossed the line at Saturday's Great Edinburgh International Cross Country, paying the price for a fast start which saw him lead the 4km race by 100m at one point before fading badly in the closing stages and ending up in third place.
But Simms played down the incident and said Farah's struggles in Edinburgh were also down to a simple tactical error on the day.
"Mo feels he perhaps went off a bit too fast in Edinburgh and, coupled with their test findings, it explains his off day," said Simms.
"Training has been going very well and he had a great run in Bolzano, Italy on New Year's Eve where he was only just out-sprinted by two of the world's best."
Kenyan Edwin Soi won the race in Italy, with Ethiopian Imanemerga Jida second.
Farah is flying out to a high-altitude camp in Kenya on Tuesday.
